BACKGROUND/AIMS: Pancreaticoduodenectomy is the procedure of choice in patients with periampullary cancers. Marked improvements in morbidity and mortality rates following pancreaticoduodenectomy have been reported in recent years. However, pancreatic leakage still occurs in 5% to 25% of patients and is a major cause of morbidity and mortality. METHODS: Between January 1990 to June 1999, eighty-two patients underwent pancreaticoduodenectomy. We compared preoperative, intraoperative characteristics as well as postoperative sandostatin usage in those patients who experienced (n=21) versus those who did not experience pancreatic leakage (n=61). Information was retrospectively collected from hospital record. RESULTS: The clinical leakage rate in this series was 25.6% (n=21). There were no significant differences in preoperative characteristics comparing those with versus those without pancreatic leakage. Among intraoperative characteristics, duct stenting and transfusions were significantly associated with the pancreatic leakage. Finally, postopeative sandostatin usage was able to reduce significantly the incidence of pancreatic leakage. CONCLUSION: Although consensus among surgeons does not exist as to opeative tenchnique and postoperative management, stenting and less bleeding as well as sandostatin usage had better results in this study.

PURPOSE: This study was conducted to estabilish the prevalence, clinical features and relationship between ECG findings and echocardiographic findings of Wolff-Parkinsion-White(WPW) syndrome in asymptomatic preschool children. METHODS: An electrocardiographic screening study was performed on 77,824 preschool children in Jeonbuk province from April, 1999 to August, 2001. Patients with WPW syndrome underwent echocardiographic study. RESULTS: Twenty three patients with WPW syndrome were discovered by electrocardiographic screening of preschool children. The prevalence rate was 2.9 per 10,000 preschool children and there was no significant sexual difference. Two patients had a history of symptoms related to tachyarrythmia. According to the ECG classification of Rosenbaum et al., five patients were type A and 18 were type B. Utilizing the criteria of Gallagher et al, right anterior, 12 patients; right anteiror paraseptal, four patients; left anteiror, three patients. Nineteen of 23 patients underwent echocardiographic study. Four of five patients with type A WPW syndrome had abnormal early systolic anterior motion of left ventricular posterior wall. Twelve of 14 patients with type B had abnormal interventricular septal motion characterized by early sytolic posterior motion immediately after inscription of the delta wave. CONCLUSION: The prevalence rate of preschool children in Jeonbuk province was 2.9/10,000. By the classification according to the electrocardiographic findings, the accessory pathway location was dominant right side than left side. In the echocardiographic study, type A WPW syndrome showed abnormal left ventricular posterior wall motion and type B WPW showed abnormal interventricular septal motion.

BACKGROUND/AIMS: We studied the patterns of recurrence after resection of relatively small hepatocellular carcinoma, defined as less than 5 cm in diameter, with tumor-free margin, and risk factor for recurrence were re-evaluated for these group. METHODS: The subjects were 25 patients who had undergone tumor removal with tumor-free margin for hepatocellular carcinoma at our department from 1995 to 1998. Tumor-free survival rates of patients with various risk factors were calculated and differences between groups were evaluated. RESULTS: The tumors recurred in 17 patients (68.0%), with 11 patients (64.7% of recurrences) recurring within 1 year of surgery. Recurrent disease was nearly intrahepatic. Univariate retrospective analysis in this study showed the absence of tumor capsule to be significant risk factor. But there is no significant difference in survival rate between capsule (+) groups and capsule (-) groups. CONCLUSION: It was concluded that small hepatocellular carcinoma has no significant difference in clinicopathologic variables except tumor capsule.

Gastric type mucinous endocervical adenocarcinomas of the uterine cervix (GAC) are a newly classified mucinous subtype with morphologically in 2014, WHO. They have a much more aggressiveness and show unusual metastatic patterns compared to usual type endocervical adenocarcinoma. They tend to present at higher stage and even in stage I, they have worse survival. Therefore, differential diagnosis of GAC from the usual type of endocervical adenocarcinoma is very important because they are related to a significant risk of recurrence and decreased 5-year disease-specific survival. Besides, GACs are mostly not associated with human papillomavirus (HPV) infection and p16 immunohistochemistry is also typically negative in GAC that is HPV-unassociated tumor. We report a very rare and interesting case of stage IB1 GAC with negative HPV DNA and p16.

Purpose: This study aimed to evaluate the natural growth of subepithelial tumors of the small bowel detected on CT. Materials and Methods: Consecutive patients who were suspected of having subepithelial tumors of the small bowel between January 2005 and December 2020 were reviewed. Eligible patients with suspected small (< 30 mm) subepithelial tumors on at least two CT evaluations were included in the analysis. The patients’ data on demographic characteristics, tumoral characteristics, and tumoral size changes during the follow-up were collected. Results: This study included 64 patients with suspected small subepithelial tumors (n = 64) of the small bowel. After a median follow-up of 15.8 months, the diameter and volume growth rates were 0.02 mm/month and 1.5 mm3/month, respectively. A significant correlation was observed between the initial size and the growth rate of the small bowel subepithelial tumors. The group of large-sized tumors (initial diameter ≥ 10 mm) tended to show lobulated contours, heterogeneous enhancement, and necrotic changes more frequently than the group of small-sized tumors (initial diameter < 10 mm). Conclusion Small bowel subepithelial tumors measuring less than 10 mm grew more slowly than those measuring 10–30 mm.

Extramammary Paget's disease (EMPD) is a rare intraepithel ial neoplasm arising in apocrine gland-bearing skin. EMPD may be regarded as a skin marker of associated malignancy because it tends to combine a variety of underlying malignancies in up to 50% of cases. Herein a case of gastric cancer diagnosed in a patient with extramammary Paget's disease of the scrotum is reported. The patient was a 65-year-old man whose chief complaint was exanthema of the right scrotum of 3 years duration. Biopsy samples taken from patient showed large, round cells with clear cytoplasm in the epidermis. The final diagnosis was EMPD of the scrotum. The extensive workups, including tumor marker, imaging studies and endoscopy to exclude associated malignancy were performed. Examination of the endoscopic gastric biopsy specimen revealed an adenocarcinoma of the stomach. On the basis of this result, a radical subtotal gastrectomy was successfully performed. This case suggests that, in cases of EMPD, the clinicians should consider the possibility of underlying malignancies and thoroughly examine not only the urogenital tract and lower gastrointestinal tract, but also the visceral organs, such as the stomach, even if there are no clinical symptoms of malignancy.

The collision tumors have been reported in various organs and represent the coexistence of two adjacent but histologically distinct tumors in an organ without any histological admixture. A gastric collision tumor is rare and most gastric collision tumors involve an adenocarcinoma colliding with a lymphoma. A 48-year-old man was referred to our hospital for an evaluation of dyspepsia and upper abdominal discomfort. Endoscopy demonstrated the presence of an ulcerative lesion in the gastric antrum. The biopsy specimens confirmed a pathological diagnosis of an adenocarcinoma. After a radical subtotal gastrectomy, a thorough Histopathological examination revealed a collision tumor: a well-differentiated adenocarcinoma in the superficial layer (mucosa, submucosa) and a poorly differentiated neuroendocrine carcinoma in the deeper layer (muscularis propria, serosa). The patient received combination chemotherapy with cisplatin and etoposide. Para-aortic lymph node enlargement was observed on the abdominal computed tomography scanning, 3 years after surgery. The patient underwent chemotherapy with TS-1, and the size of lymph nodes was reduced. The patient continues to do well after a follow up period of 5 years 3 months. We report this case of gastric collision tumor (adenocarcinoma and neuroendocrine carcinoma) with a brief review of the relevant literature.

PURPOSE: Total gastrectomy is followed by weight loss in the majority of patients, but the reason for this is not clear. Ghrelin, a novely isolated gastric hormone, exerts orexigenic activity. If a circulating ghrelin participates in the adaptive response to weight loss, the weight loss induced by total gastrectomy may be accompanied by impaired ghrelin secretion. METHODS: The blood was collected from gastric cancer patients who have undergone gastric resection, preoperatively and immediately after resection, on the 1st, 3rd and 7th postoperative day. The correlation of the preoperative plasma ghrelin concentration with gender, age and BMI were analyzed. The concentration changes of plasma ghrelin were observed serially after dividing gastrectomized patients into the subtotal gastrectomy group, the total gastrectomy group, and the proximal gastrectomy group. RESULTS: Although statistically not significant, the plasma ghrelin concentration was negatively correlated with age and BMI. In the subtotal gastrectomy group, nadir ghrelin was 48.4 +/- 23.6% of the preoperative value after gastric resection and then gradually increased to 82.4 +/- 19.9% on the 7th postoperative day. In the total gastrectomy group, nadir ghrelin was 36.9 +/- 10.4% of the preoperative value after gastric resection and remained 20.9 +/- 10.9% on the 7th postoperative day. In the proximal gastrectomy group, nadir ghrelin was 29.4 +/- 4.6% after gastric resection, which was followed by a gradual recovery. However, the recovery rate was steadier than compare to the subtotal gastrectomy group, as the concentration was 41.8 +/- 23.1% even on 7th postoperative day. CONCLUSION: The principal site of the ghrelin synthesis is stomach which contributes 60~70% to the circulating concentration of ghrelin. In the case of subtotal gastrectomy, ghrelin production is compensated by the remnant stomach. For this reason total gastrectomy is associated with suppressed ghrelin levels and it possibly contribute to the weight loss.

PURPOSE: The risk factors of pseudomembranous colitis (PMC) are well known. However, there have been no studies of PMC after gastrointestinal operation. The aim of this study was to evaluate the risk factors and to establish the guiding principles for PMC after gastrointestinal operation. METHODS: We performed a retrospective study of 39 PMC patients after gastrointestinal operation from January 2004 to December 2008. A control group of one hundred and seventeen matched to a PMC group by date of operation was chosen in a random fashion. Preoperative, operative, and postoperative factors of PMC were evaluated. RESULTS: The incidence of PMC after gastrointestinal operation was 0.63%. On univariate analysis, among preoperative factors, albumin, PT-INR and neutropenia were significant risk factors for PMC. There was no difference in the operative factors. Among postoperative factors, duration of cephalosporin, aminoglycoside, H2 blocker administration were significant risk factors for PMC after gastrointestinal operation. And transfusion, duration of NPO, length of stay in intensive care unit (ICU) and postoperative intraabddominal abscess, pneumonia were also significant risk factors. On multivariate analysis, the independent risk factors for PMC after gastrointestinal operation were duration of aminoglycoside administration, transfusion volume and length of stay in ICU. When period of study was divided by three months, incidence of PMC at a specific period was high. After limiting of prophylactic antibiotics, incidence of PMC fell to 0.36%. CONCLUSION: To prevent PMC after gastrointestinal operation, we need sustained efforts to establish stricter guidelines about prophylactic antibiotics and transfusion, and to minimize length of stay in ICU.
